Digestive cancer represents a severe public health problem, being one of the main causes of death. It is considered a multifactorial disease, with hereditary predisposition, environmental factors, and other factors involved in carcinogenesis. Both the evolution and the pathogenesis of digestive neoplasms remain incompletely elucidated. As a multifactorial disease, it can be approached by taking into account the biopsychosocial influences via enteric nervous system. Many peptides and non-peptides having a neurotransmitter role can be found in the enteric nervous system, which can influence the neoplastic process directly or indirectly by affecting some angiogenic, growth, and metastasis factors. However, neurotransmitters can ...

Department of Radiology Posters
Neoadjuvant chemotherapy is a well-established treatment option for patients with non-metastatic breast cancer. The patient response is correlated with survival. However, the optimal method for monitoring neoadjuvant therapy response has not been established. One factor that may affect the response of neoadjuvant therapy is the interstitial fluid pressure (IFP). Increased IFP prevents an effective delivery of therapeutic agents and reduces the efficacy of the therapy. Recently, subharmonic-aided pressure estimation (SHAPE) using contrast-enhanced ultrasound (CEUS) has been developed and its potential was demonstrated in animals as a non-invasive technique for IFP measurements. The SHAPE method estimates IFP based on the ...

❖ Uveal melanoma is the most common primary intraocular malignant tumor in adults.
❖ Up to half of all patients develop systemic metastases, with liver involvement in >90% of patients.1
❖ Various liver-directed, locoregional therapies (i.e. chemoembolization, immunoembolization, radioembolization, and ablation) have played a significant role in prolonging the lives of patients with metastatic uveal melanoma.2
❖ Elevated bilirubin levels are typically considered a relative contraindication for lobar hepatic arterial embolization treatment, given mainly the increased risk of precipitating hepatic failure.
❖ Gilbert's syndrome, also known as benign unconjugated hyperbilirubinemia, is a hereditary disorder of bilirubin conjugation. Gilbert’s syndrome ...

Expression Of Ps2 In Prostate Cancer Correlates With Grade And Chromogranin A Expression But Not With Stage, Hammad Ather, Farhat Abbas, Nuzhat Faruqui, M Israr, Shahid Pervez
Background: The biological potential of prostate cancer is extremely variable. Particular interest is focused on markers not expressed in normal prostatic tissues. pS2 protein expression has been demonstrated in a range of malignant tissues in an oestrogen-independent pathway. Recently, it has been demonstrated that pS2, in prostate cancer, is closely associated with neuro-endocrine differentiation. In the present study, we have analyzed, the potential of Neuro-endocrine and pS2 (TFF1) expression in human prostate cancer determined by immunohistochemistry, in primary adenocarcinoma of the prostate and attempted to correlate this with the clinico-pathologic features of the patient and neuroendocrine expression.
Methods: Ninety-five malignant ...

To investigate the potential functional cooperation between p27Kip1 and p130 in vivo, we generated mice deficient for both p27Kip1 and p130. In p27Kip1−/−;p130−/− mice, the cellularity of the spleens but not the thymi is significantly increased compared with that of their p27Kip1−/− counterparts, affecting the lymphoid, erythroid, and myeloid compartments. In vivo cell proliferation is significantly augmented in the B and T cells, monocytes, macrophages, and erythroid progenitors in the spleens of p27Kip1−/−; p130−/− animals. Immunoprecipitation and immunodepletion studies indicate that p130 can compensate for the absence of p27Kip1 in binding to and ...

Molecular And Cellular Biology Of Prostate Cancer, El-Nasir Lalani, Marc Elie Laniado, Paul David Abel
El Nasir Lalani
Prostate cancer is an enigmatic disease. Although prostatic-intraepithelial neoplasia appears as early as the third decade and as many as 80% of 80 year old men have epithelial cells in their prostate that fit the morphological criteria for cancer, only about 10% of men will ever have the clinical disease and less than 3% will die from it. There have been no significant proven interventions which have altered the natural history of the disease since hormone down regulation was introduced in the 1940s and new research has been poorly supported. There is however an urgent need to develop new criteria ...
Efficient Immortalization Of Luminal Epithelial Cells From Human Mammary Gland By Introduction Of Simian Virus 40 Large Tumor Antigen With A Recombinant Retrovirus, Bartek J, Bartkova J, Kyprianou N, El-Nasir Lalani, Staskova Z, Shearer M, Chang S, Taylor Papadimitriou J
El Nasir Lalani
When defined in terms of markers for normal cell lineages, most invasive breast cancer cells correspond to the phenotype of the common luminal epithelial cell found in the terminal ductal lobular units. Luminal epithelial cells cultured from milk, which have limited proliferative potential, have now been immortalized by introducing the gene encoding simian virus 40 large tumor (T) antigen. Infection with a recombinant retrovirus proved to be 50-100 times more efficient than calcium phosphate transfection, and of the 17 cell lines isolated, only 5 passed through a crisis period as characterized by cessation of growth. When characterized by immunohistochemical staining ...

Tumor-Associated Stromal Cells As Key Contributors To The Tumor Microenvironment., Karen M. Bussard, Lysette Mutkus, Kristina Stumpf, Candelaria Gomez-Manzano, Frank C. Marini
Department of Cancer Biology Faculty Papers
The tumor microenvironment is a heterogeneous population of cells consisting of the tumor bulk plus supporting cells. It is becoming increasingly evident that these supporting cells are recruited by cancer cells from nearby endogenous host stroma and promote events such as tumor angiogenesis, proliferation, invasion, and metastasis, as well as mediate mechanisms of therapeutic resistance. In addition, recruited stromal cells range in type and include vascular endothelial cells, pericytes, adipocytes, fibroblasts, and bone-marrow mesenchymal stromal cells. During normal wound healing and inflammatory processes, local stromal cells change their phenotype to become that of reactive stroma. Under certain conditions, however, tumor ...

Seton Hall University Dissertations and Theses (ETDs)
Over the past two decades, advances in RNA structural biology have improved our understanding of the structures and folding properties of naturally occurring RNAs. RNA sequences and structures participate in many specific biological functions, such as those performed by messenger RNA (mRNA), ribosomal RNA (rRNA), transfer RNA (tRNA), micro RNA (miRNA), short-interfering RNA (siRNA), small nuclear RNA (snRNA) and many others. The noncoding RNAs, such as siRNA, do not express proteins but have been utilized in a wide range of applications, including RNA interference (RNAi) and the regulation of mRNA expression. These important biological functions have been implemented in gene ...

Case Study Of Persons With Cancer Participating In A Community-Based Exercise Program: An Exploration Of Meaning And Change, Barbara K. Haas, Melinda Hermanns, Christina Melin-Johansson
The Qualitative Report
Increasingly, research supports the importance of incorporating exercise into the cancer care paradigm. While quantitative studies have substantiated the significant effects of exercise on physical functioning, the individual’s perspective of participating in an exercise program has rarely been considered. The purpose of this study was to explain the impact of a community based exercise program on the lives of persons with cancer and their caregivers. Based on Bandura’s Social Cognitive Theory, a single explanatory case study with multiple embedded units of analyses was conducted. Interviews were conducted with 10 individuals representing participants with cancer, their caregivers, and health ...

The treatment of metastatic RCC has undergone a paradigm shift over the past 5 years from biologic response modifiers to new targeted therapies. Historically, response rates for the biological response modifiers, aldesleukin ...
Tolerability Of Induction Chemotherapy Dosing Practices In Acute Myeloid Leukemia Patients, 2016 Butler University
Tolerability Of Induction Chemotherapy Dosing Practices In Acute Myeloid Leukemia Patients, Kaylene M. Peric, David J. Reeves
For patients with high body surface areas (BSA), differing chemotherapy dosing strategies have been utilized in attempts to reduce toxicity. In a retrospective evaluation, we compared the effects of chemotherapy dosing in acute myeloid leukemia patients with high BSA (>2 m2) who received capped doses (n = 12) to those who received uncapped doses (n = 24), and to patients with BSA ≤ 2 m2 (n = 42). There were no statistically significant differences among groups (BSA ≤ 2 m2, BSA > 2 m2 capped, and BSA > 2 m2 uncapped) in the incidences of febrile neutropenia (85.7, 66.7, and ...

Retrospective Evaluation Of Venous Thromboembolism Prophylaxis In The Adult Cancer Population, David J. Reeves, Chin Y. Liu
Study objectives. Hospitalized cancer patients are at an increased risk for venous thromboembolism (VTE) and it is recommended they receive pharmacologic prophylaxis unless otherwise contraindicated. The majority of data supporting this recommendation comes from sub-group analyses and extrapolation of data gathered in general medical/surgical patients. This study seeks to assess the safety and efficacy of VTE prophylaxis in cancer patients admitted to our institution.
Methods. Charts of patients 18—89 years of age receiving VTE prophylaxis with unfractionated heparin, low molecular weigh heparin, or fondaparinux while admitted to Karmanos Cancer Center between September and October 2007 were retrospectively reviewed ...

The World Health Organization has developed and implemented the Fracture Risk Assessment Tool (FRAX) to predict the ten year risk of a major fracture & hip fracture. Additionally, the National Comprehensive Cancer Network and the National Osteoporosis Foundation have developed osteoporosis guidelines. This study aims to characterize the fracture risk (based on the FRAX tool) and the current management of bone health based on national guidelines compliance.
Methods. A retrospective chart review of patients receiving a LHRH ...
Nanobubbles Provide Theranostic Relief To Cancer Hypoxia, 2016 Purdue University
Nanobubbles Provide Theranostic Relief To Cancer Hypoxia, Christopher M. Long, Pushpak N. Bhandari, Joseph Irudayaraj
The Summer Undergraduate Research Fellowship (SURF) Symposium
Hypoxia is a common motif among tumors, contributing to metastasis, angiogenesis, cellular epigenetic abnormality, and resistance to cancer therapy. Hypoxia also plays a pivotal role in oncological studies, where it can be used as a principal target for new anti-cancer therapeutic methods. Oxygen nanobubbles were designed in an effort to target the hypoxic tumor regions, thus interrupting the hypoxia-inducible factor-1α (HIF-1α) regulatory pathway and inhibiting tumor progression. At less than 100nm, oxygen nanobubbles act as a vehicle for site-specific oxygen delivery, while also serving as an ultrasound contrast agent for advanced imaging purposes. Through in vitro and in vivo studies ...

A Phase I Dose-Escalation Study Of The Braf Inhibitor Vemurafenib In Combination With The Mtor Inhibitor Everolimus In Subjects With Advanced Cancer, Javier Munoz
UT GSBS Dissertations and Theses (Open Access)
Vemurafenib has been approved in the United States for the treatment of relapsed or refractory BRAF mutation positive malignant melanoma and is being investigated in various other malignancies. The RAS/RAF/MEK/ERK (MAPK) pathway is critical to cell proliferation in many human cancers. The mTOR inhibitors are well known to exert profound anticancer effects across malignancies through inhibition of the PTEN/PI3K/AKT/mTOR (mTOR) pathway. We hypothesize that the toxicity profile of the combination of vemurafenib and everolimus will be well tolerated. The primary objective is to find the maximum tolerated dose (MTD) and the toxicity of the ...
Epigenetic Modulation In Braf Mutated Metastatic Colorectal Cancer, 2016 The University of Texas Graduate School of Biomedical Sciences at Houston
Epigenetic Modulation In Braf Mutated Metastatic Colorectal Cancer, Van Morris
UT GSBS Dissertations and Theses (Open Access)
Introduction: BRAF V600E mutations are associated with poor clinical outcomes for patients with metastatic colorectal cancer (mCRC). Unlike other tumors with the same mutation, BRAF inhibitors are ineffective as monotherapy. CRC tumors with BRAF V600E mutations are associated with global hypermethylation, which may turn off tumor suppressor gene expression. We studied demethylation in BRAF V600E mCRC to restore sensitivity to BRAF inhibitors.
Methods: Tumor databanks were investigated for genes differentially expressed according to BRAF mutation status to identify genes which may be particularly susceptible to epigenetic influence. Mouse xenograft models of BRAFV600E mCRC were treated with vemurafenib or azacitidine, alone ...
